Calling an extension lets you reach a specific person or department within a larger phone system. To call an extension, you first dial the main business number, then enter the extension number when prompted — usually by pressing a key or waiting for the auto attendant menu.
RingVersa makes extensions easy starting at $14.95 per user per month. Each team member gets their own extension and direct number, callers can dial extensions from the auto attendant, and you can transfer calls between extensions instantly.
Key Features
Everything you need for professional business communication
Dial Main Number First
Call the business's main number, then enter the extension when prompted by the auto attendant.
Wait or Press a Key
Most systems prompt you to dial the extension or press a key to reach a directory.
Pause Dialing
On smartphones, insert a pause (comma) between the main number and extension to auto-dial both.
Direct Dial
With RingVersa, each extension also has a direct number so callers can bypass the main menu.
